Bacteriological quality and antibiogram study of bacteria from "suya" and smoked fish (Clarias gariepinus) in Dutsin-Ma, Katsina State, Nigeria

Abstract

Introduction"suya" and smoked fish are cherished food delicacies in Nigeria, but can be a source of dissemination of Multi-drug Resistant (MDR) bacteria. Moreover, there are limited studies on these MDR bacteria from Dutsin-Ma. Therefore, this study examined the bacteriological qualities and antibiogram profiles of bacteria in these foods from this area in Nigeria.MethodsTwenty samples of each of "suya" and smoked fish were collected from the study areas and microbiologically analyzed. Total viable count, coliform count, characterization and identification of bacteria were carried out by standard microbiological techniques.ResultsFindings revealed that "suya" samples possessed the highest total viable bacteria count (3.4×105 to 7.7×105 cfu/g) and coliform count (2.1×105 to 6.2×105 cfu/g). A total of 85 and 78 bacteria were isolated from "suya" and smoked fish samples respectively. E. coli (24.7% and 24.4%) was the most frequently isolated from each sample respectively. Highest (66.7%) resistance to each of cefuroxime, gentamicin, amoxillin/clavulanate and ciprofloxacin were observed among E. coli from "suya". MDR phenotypes commonly isolated was resistance to ceftazidime, cefuroxime, ampicillin, ciprofloxacin, augmentin and nitrofurantoin.ConclusionThese studies showed the presence of MDR bacteria in samples, hence, raise the need for improved production hygiene and public health awareness.

Prevalence of multi-drug resistant Pseudomonas aeruginosa isolated from selected residential sewages in Dutsin-Ma, Katsina State, Nigeria

“…Presumptively, blue-green pigment colonies were aseptically picked and stored on nutrient agar slants for further biochemical characterization. 11 …”

“…Previous studies in Nigeria have been centered on analyzing the prevalence of multidrug-resistant P. aeruginosa from clinical environments and abattoir/industrial wastewater effluents. 9 , 11-15 However, to the best of our knowledge there is scanty information on prevalence of antibiotic resistant P. aeruginosa from residential sewage in Dutsin-Ma, Katsina State, Nigeria. Improper disposal of sewage has been an issue of great concern in developing countries including Nigeria, with Dustsin-Ma town (in Katsina state) as a focal point.…”

Antibiotic resistance of Bacillus species isolated from hawked ‘suya’ meat sold in Kaduna metropolis, North-Western Nigeria

“…The presence of Bacillus species in the suya samples may be due to contamination from long exposure to air during hawking as reported by Adesoji et al [11] and this air might have polluted with different types of microorganisms. The presence of Bacillus cereus is of public health importance because it is frequently associated with cases of food poisonings as reported by Agwa et al [12] and Osman et al [6].…”

Prevalence of multi-drug resistant bacteria associated with foods and drinks in Nigeria (2015-2020): A systematic review

“…Adesoji et al . ( 2019a ) also reported the presence of MDR bacteria which were resistant to Ceftazidime, Cefuroxime, Gentamicine, Ciprofloxacin, Ofloxacin, Amoxycillin clavulanate, Nitrofurantoin, Ampicillin, Erythromycin, Cloxacillin (5μg), Augmentin and Ceftriaxone in both smoked fish and suya sampled, including Staphylococcus sp., Escherichia sp., Enterobacter sp., Shigella sp., Bacillus sp., Salmonella sp. and Proteus sp.…”
